' IMPROVED BUNG FOR CASKS.

Specification Aforming part of Letters Patent No. 49,473, dated August l5, 1865.

To alt whom it may concern:

Be it known that I, MICHAEL HICKEY, of the city of Boston, State of Massachusetts, have invented a new and useful device, being a Permanent Bung for Oasks, and l declare the following speciiication, with the drawings forming a part thereof, to bea full and complete description ot' my invention.

Figurel represents the apparatus in perspective. Fig. 2 representsitln section through its center.

Similar letters denote the same parts ofthe apparatus.

lt is well known to brewers and others, who in their business have occasion to use casks over and over again, that there is a considerable expense attending the furnishing of new bungs, and, besides this, that by the repeated process of driving them in and springing them out the bung-hole becomes so worn as to make it necessary to replace the bung-stave, which is bot-h a troublesome and expensive ai'air.

To furnish apermanent bung and attach it so as to avoid the wear of thesta `isthe object of `myinventiony` A repr ents theft hole. (Joncentricwt y y, y, y g` n down, fro one-thirdto one-halfithei i of the stave, a cylindrical countersiuk, so as to form around the hole a level shoulder or shelf, c c. Y The bung is made of metal, and is a cylindrical head, O, in diameter nearly fitting the i couutersinkdiole, with or without a less cylinder, K, nearly titting the bung-hole. From this head projects downwarda stem or rod,E, having a screw-thread upon its lower end.

Fastened to the stave there is a metal loop, H, 'dropping some distance below the hunghole, in the bottom ot' whichthere is a screwsocker, D, tted to the rod'E. This loop is made with its outer edge beveled, and of such depth as to permit the free passage of and prevent the retention of the dregs of the cask when being ein ptied for the purposes ot' cleansing.

To insure a perfect closing of the bung-hole a ring, a, of india-rubber, gotta-percha, or other suitable material, is placed between the bung and the shelf c c.

The mode of using the bung is sutiiciently manifest withoutdescription.

It will be seen "Troni this description of its construction thatthe hung must he a lasting article, and prevent fora long time any wear of the bung-stave. ,1,

What l claim as my invention, and desire to secure hy Letters Patent, is

A metal bung, with its ring a and its loop H, formed, fitted, and secured to the stave,isub

stantially in the manner and form and for the' purposes set forth in this specitieation.

MICHAEL HIOKEY.
